Electrical Bathroom Zones Explained Zone 0 This zone covers the base of the shower and the inside of the bath, all light fittings used here must be at least IP67 and 12V. What is Low Voltage? According to the Australia and New Zealand Standards - Electrical Wiring Rules AS/NZS 3000:2018 low voltage is anything "Not exceeding 12 Volts AC or 30 Volts ripple-free DC". What does "Wet Area Suitable" mean? Products that are "Wet Area Suitable" have a suitable IP (Ingress Protection) rating that enables them to be installed in what is classified as Zone 1 in.
To keep things simple, NZ regulations divide the various areas in a bathroom into zones. Zone 0: Inside the bath or shower area - No electrical equipment should be installed in this area unless specially designed to be submerged, such as waterproof lighting. Zone 0: Inside the bath or on the shower base - no towel rails or electrical fittings may be installed.
Zone 1: The area directly above the bath or inside a shower enclosure, up to 2.25 m high. Electrical Safety in bathrooms divides into four zones. In Zone '0' which defines being within in the sink bowl, bath tub or shower bowl any electrical appliance must be IP67 (full immersion capable) and low voltage.
Zone 1 is the splash zone above a bath or within a shower enclosure and extends from the floor to 2.25m up the walls. This is split into zones Zone 0: Inside the bath or shower. These must be SELV (Low voltage i.e.
12V Max). Minimum IP rating IPx7 (IP67) Zone 1: Above the bath or shower to a height of 2.85m. Minimum rating of IPx5 (IP65), there is a chance jets of water may hit the fitting.
Zone 2: Area stretching 0.6m outside the bath or shower. For electrical fittings the bathroom is divided into zones into by the NZ Electrical Code of Practice as in diagrams below. IP ratings required explained.
Who defines the requirements for bathroom lighting zones in Australia? In Australia, bathroom lighting requirements are governed by the Electrical Wiring Regulations (AS/NZS 3000:2018) and the Building Code of Australia (BCA). The Australia and New Zealand Standard AS/NZS 3000:2018 identifies the zones in a bathroom and the IP rating required for electrical items installed in each zone. 1.
